About the ending

Just a quick question. At the end of the movie they spell out 'hello' on the ground and see the aircraft. I think this implies that the virus hasn't in fact spread around the globe. But the weird thing about all this is that why is the aircraft in Finnish army colors and when we hear the pilot talking, he speaks Finnish and at the end says: "send a helicopter". There were no subtitles in English for this part (at least in the cinema where I went to see it).
Finland isn't even a member state of NATO, so why would they send an aircraft to England. That would be the first time ever. Does this mean that the virus has actually spread worldwide, but Finland was spared? Or perhaps Finland is among few periphery countries that the virus never reached?
